Write a Java program that will split the following string $($the code should be able to handle any number of

commas$)$ and store the elements in an Array or Array List:

String str $=$ "Apple, Orange, Pear, Peach";

Your code will create an array of strings: $\{"$Apple$",$ "Orange", "Pear", "Peach"$\}$

Now, write a code to create a new string from the array you just created:

String str$2=$ "Apple$--$Orange$--$Pear$--$Peach";

Important: You cannot use any built$-$in methods of the String class.

Do at home:

Use the codes you developed to read lines $($comma$-$separated$)$ from the file input.csv darr$$ and write the lines in a

file called output.txt in the format of the second string above.
